POWER DETECTORS - SMT v02.0913 Typical Applications The HMC948LP3E is ideal for: • Point-to-Point Microwave Radio • VSAT • Wideband Power Monitoring • Receiver Signal Strength Indication (RSSI) • Test & Measurement HMC948LP3E 54 dB, LOGARITHMIC DETECTOR, 1 - 23 GHz Features Wide Input Bandwidth: 1 to 23 GHz Wide Dynamic Range: 54 dB up to 23 GHz Single Positive Supply: +3.3V Excellent Stability Over Temperature Fast Rise / Fall Time: 5 / 7 ns 16 Lead 3x3 mm SMT Package: 9 mm² Functional Diagram General Description The HMC948LP3E Logarithmic Detector converts RF signals at its input, to a proportional DC voltage at its output. The HMC948LP3E employs successive compression topology which delivers high dynamic range over a wide input frequency range. As the input power is increased, successive amplifiers move into saturation one by one creating an approximation of the logarithm function. The output of a series of square law detectors is summed, converted into the voltage domain and buffered to drive the LOG OUT output. The HMC948LP3E provides a nominal logarithmic slope of +14.2 mV/dB and an intercept of -111 dBm at 23 GHz. Ideal as a log detector for high volume microwave radio and VSAT applications, the HMC948LP3E is housed in a compact 3x3 mm RoHS compliant SMT plastic package.
